Reactant Concentration Formula:
From: | To: |
Definition: This calculator determines the concentration of reactant in vessel i based on the concentration in the previous vessel, reaction rate constant, and adjusted retention time.
Purpose: It helps chemical engineers and researchers analyze reaction progression in series of vessels or reactors.
The calculator uses the formula:
Where:
Explanation: The formula calculates how reactant concentration decreases as it moves through successive vessels in a first-order reaction system.
Details: Accurate concentration calculations are essential for reaction optimization, process control, and predicting product yields in continuous flow systems.
Tips: Enter the reactant concentration from the previous vessel, the reaction rate constant, and the adjusted retention time. All values must be > 0.
Q1: What is a first-order reaction?
A: A reaction where the rate depends linearly on the concentration of one reactant.
Q2: How do I determine the rate constant?
A: The rate constant can be determined experimentally by measuring reaction rates at different concentrations.
Q3: What affects the adjusted retention time?
A: Column length, mobile phase flow rate, and interactions between the component and stationary phase.
Q4: Can this be used for batch reactors?
A: This specific formula is designed for continuous flow systems with vessels in series.
Q5: How does vessel number affect concentration?
A: Each successive vessel will show decreasing reactant concentration according to this relationship.
